Choosing the right sprayer tank matters: it affects how efficiently you treat lawns, gardens, and acreage — from spot-treating weeds to mixing fertilizer and hauling water. These recommendations come from hands-on testing, expert evaluation, and careful review of consumer feedback to match real-world needs.
Considerations
I ranked tanks by real-world usage, build quality, plumbing and mounting options, capacity, and value. Testing included filling/draining cycles, checking fittings and seals, mounting/security features, and evaluating material durability against UV and common lawn chemicals. I also weighed expert opinions and verified customer reliability trends to reduce selection bias.
Key factors considered:
- Material & durability (rotomolded polyethylene, HDPE) — affects impact, UV and chemical resistance.
- Fittings & drainage — bulkhead size, drain type, included siphon/elbow, and tethered caps.
- Mounting & installation — strap grooves, horizontal vs vertical design, rack compatibility.
- Capacity & portability — range from handheld tanks to 50+ gallon storage.
- Price vs features — value for users on a budget or requiring commercial durability.
2-Gallon Concentrate Tank
Compact 2-gallon concentrate tank designed for easy replacement and precise mixing. Ideal for homeowners and small-plot applicators who want a lightweight, labeled container to pair with compatible spray systems for spot treatments and concentrate dispensing.
Perfect for homeowners and small operators, this 2-gallon concentrate tank is lightweight, clearly labeled, and designed as a drop-in replacement for compatible sprayer heads. It excels at saving water by enabling concentrated mixes and features measurement markings and a strainer to reduce clogs. Downsides: limited capacity and best suited for spot treatments rather than large-area spraying.
ATV Boomless Spray Kit
A practical ATV/UTV boomless sprayer kit with corrosion-proof polyethylene tank and easy strap-mount design. Great for acreage, fences, and trails — offers portability and a complete spray system without costly add-ons.
This spray system bundles a corrosion-resistant polyethylene tank with a 2" spray assembly designed to strap to ATV racks or cargo beds. It’s a strong value: you get mobility, a boomless spray pattern suitable for fence lines and small pastures, and durable construction without spending a premium. It’s not intended for large-scale commercial spraying but is an excellent mid-sized solution for farms, ranches, and properties where maneuverability matters.
RTS 50-Gallon Rotomolded Tank
Heavy-duty rotomolded polyethylene 50-gallon tank with vented cap, molded gallon graduations, strap grooves, and siphon elbow. Built for long-term outdoor use — an excellent choice for professional water and non-flammable liquid storage.
This rotomolded polyethylene tank stands out for durability and thoughtful user features: a vented cap for pump hookup, molded grad strips to read gallons, strap grooves for secure mounting, a preinstalled bulkhead fitting, and a siphon elbow for thorough drainage. Manufactured in the USA and covered by a one-year warranty, it handles impact, weather, and typical garden chemicals with confidence. Consider the footprint and the need for a compatible pump — this is a capacity-first, longevity-first purchase.
25-Gallon Horizontal Tank
A 25-gallon heavy-duty horizontal tank made of HDPE, engineered for stable mounting and industrial use. It features a large fill cap and a 3/4" outlet drain — a compact, workhorse option for contractors and serious gardeners.
This 25-gallon horizontal tank balances commercial-grade durability with a compact footprint. Constructed from high-density polyethylene rated for common fluids, it includes a 6" fill cap (4.5" access) and a 3/4" outlet drain for easy hookup and maintenance. The horizontal profile improves stability when mounted on trailers or racks, making it ideal for contractors and landscapers who need a dependable mid-size tank. Best suited for users who want rugged performance without the bulk of larger rotomolded tanks.
